Product details

20 MHz AVR core with industrial temperature range

The Microchip ATMEGA3208-MFR is an 8-bit AVR microcontroller from the megaAVR® 0 series, which includes Functional Safety (FuSa) documentation support.

Memory and peripheral budget for control applications

The 256-byte EEPROM stores calibration constants or configuration parameters that survive power loss without external FRAM.

Package and thermal considerations for the 32-VFQFN

The ATMEGA3208-MFR comes in a 32-VFQFN package with an exposed pad (5x5 mm body).

Frequently asked questions

What is the difference between ATMEGA3208-MFR and ATMEGA3208-MF?

The suffix -MFR indicates Tape & Reel packaging, while -MF typically denotes tray or tube packaging. The silicon and electrical specs are identical.

Is ATMEGA3208-MFR compatible with Arduino?

The megaAVR® 0 series is supported by Microchip's MPLAB X IDE and the Arduino core via third-party board packages, but official Arduino compatibility is not guaranteed by the manufacturer.
